The difference between the actual and experimental value is always the absolute value of the difference. |Experimental-Actual|/Actualx100 so it doesn't matter how you subtract. Step 2: Divide the error by the exact value (we get a decimal number) Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign) As Here is how to calculate percent error, with an example calculation.Percent Error FormulaFor many applications, percent error is expressed as a positive value.

WÃ¤hle deine Sprache aus. The absolute value of a number is the value of the positive value of the number, whether it's positive or negative. This is also called the accepted, experimental or true value.Note due to the absolute value in the actual equation (above) there are two value. The result of the difference is positive and therefore the percent error is positive.
